Kringlublaðið [the Kringla leaf] is a vellum manuscript leaf, dated c. 1260, the only one to survive from a manuscript called Kringla that was destroyed in the 1728 great fire of Copenhagen. Kringla was well known as the best manuscript of the great set of historical sagas known as Heimskringla, written by the thirteenth-century writer and statesman Snorri Sturluson (1178-1241). The leaf was found in the Royal Library in Stockholm, and is likely to have been in Stockholm from the late seventeenth century. During his state visit in Iceland in 1975 King Carl Gustav XVI presented the manuscript leaf to the Icelandic people for preservation in the National Library. The text to be found on the leaf is from Óláfs saga helga [the saga of King Ólafur the Saint], the longest of Heimskringla's 16 sagas about the kings of Scandinavia.
